Efficient multiple occlusion queries for scene graph systems
Dirk Staneker, Dirk Bartz, Wolfgang Strafler · 2004
Image space occlusion culling is an useful approach to reduce the rendering load of large polygonal models. Like most large model techniques, it trades overhead costs with the rendering costs of the possibly occluded geometry. Meanwhile, modern graphics hardware supports occlusion culling. Unfortunately these hardware extensions consume fillrate and latency costs.
